After over one year of working out 4-5 times a week, I have gone up in jacket size from 38 to 40. Â Normally this would be cause for great rejoicing, but I have also outgrown a suit that I recently purchased. Â The jacket cannot be altered because there is not enough material. Â Fortunately, I didn't pay that much for the suit both because I rarely get the opportunity to wear one (my office is business casual 5 days a week) and I thought that I might outgrow it soon. Â I am now in the market for some suits and sportscoats so I can bring a more upscale look to the office, but I am afraid of outgrowing those as well. Â Should I hold off on buying anything really nice or take the chance that my build will not fluctuate too much? Â FYI, I am currently between 170 and 175 pounds (depending on the time of day) and I don't see myself adding more than 5 to 10 pounds of muscle. Â Although it will only be a rough estimate, I am particularly interested in hearing from anyone who has an athletic build between 175 and 185 pounds -- what size jacket do you wear?
